Natural establishment of woody species on abandoned agricultural fields in the lower Mississippi Valley: first- and second-year results
The natural establishment of woody seedlings on abandoned agricultural fields was investigated at sites in Louisiana and Mississippi. Series of disked and undisked plots originating at forest edges and oriented in cardinal directions were established on fields at each site. During the firest 2 years, seedling recruitment was dominated by sweetgum, sugarberry, and elms at both sites. Seedling estab

Effects of flooding regime, mycorrhizal inoculation and seedling treatment type on first-year survival of Nuttal Oak (Quercus nuttallii Palmer)
Three different types of Nuttall oak (Quercus nuttallii Palmer) seedlings were planted on floodprone, former cropland in Mississippi, Louisiana, and Texas. The three types of 1+0 seedlings planted at each site in January and February of 1995 were bareroot seedlings, seedlings grown in 164 square centimeters plastic containers, and container grown seedlings inoculated with vegetative mycelia of Pis

Characterization of an old-growth bottomland hardwood wetland forest in Northeast Texas: Harrison Bayou
Most wetland losses in the southern region over the past 200 years have occurred in bottomland hardwood forests. By 1980 the original extent of palustrine bottomland in Texas had been reduced by 63%, from roughly 16 to 6 million acres. Additional losses have occurred during more recent years as a result of conversion to agriculture and timber harvests; these factors and the need to supply new hard

Guidelines for quality assurance and quality control of fish taxonomic data collected as part of the National Water-Quality Assessment Program
Fish community structure is characterized by the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program as part of a perennial, multidisciplinary approach to evaluating the physical, chemical, and biological conditions of the Nation's water resources. The objective of quality assurance and quality control of fish taxonomic data that are collected as part of the NAWQA Program is

Key areas for wintering North American herons
Nearly all North American heron populations are migratory, but details of where they winter are little known. Locations where North American herons winter were identified using banding recovery data. North American herons winter from Canada through northern South America but especially in eastern North America south of New York, Florida, California, Louisiana, Texas, Mexico and Cuba, these areas

Classifying coastal resources by integrating optical and radar imagery and color infrared photography
A progressive classification of a marsh and forest system using Landsat Thematic Mapper (TM), color infrared (CIR) photograph, and ERS-1 synthetic aperture radar (SAR) data improved classification accuracy when compared to classification using solely TM reflective band data. The classification resulted in a detailed identification of differences within a nearly monotypic black needlerush marsh. Ac

Comparative sensitivity of five species of macrophytes and six species of algae to atrazine, metribuzin, alachlor, and metolachlor
This study determined the relative sensitivity of five species of aquatic macrophytes and six species of algae to four commonly used herbicides (atrazine, metribuzin, alachlor, and metolachlor). Toxicity tests consisted of 96-h (duckweed and algae) or 14-d (submerged macrophytes) static exposures. The triazine herbicides (atrazine and metribuzin) were significantly more toxic to aquatic plants tha

Estimates of annual survival probabilities for adult Florida manatees (Trichechus manatus latirostris)
The population dynamics of large, long-lived mammals are particularly sensitive to changes in adult survival. Understanding factors affecting survival patterns is therefore critical for developing and testing theories of population dynamics and for developing management strategies aimed at preventing declines or extinction in such taxa. Few studies have used modern analytical approaches for analyz

Common and scientific names of aquatic invertebrates from the United States and Canada: Mollusks
This edition of Common and Scientific Names of Invertebrates from the United States and Canada: Mollusks represents the efforts of 15 molluscan taxonomic specialists in compiling a comprehensive checklist of the mollusks found in North America and Canada and their vernacular names. Built upon the success of the first edition, the authors have updated the nomenclature to reflect recent phylogenetic
